[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example

[0027] See also Figure 1-5The present invention provides the following technical solutions: A computer-controlled plant protection system, comprising a central control unit 1, a plant protection vehicle 6 wirelessly connected to the central control unit 1, the plant protection vehicle 6 comprising a vehicle-mounted control unit 2, a lifting structure 3, and a plant protection device for spraying, watering and loosening the soil arranged on the lifting structure 3, the plant protection device comprising a loosening unit 4 and a spray unit 5, the loosening unit 4 and the spray unit 5 being electrically connected to the vehicle-mounted control unit 2 for the execution of the loosening unit 4 and the spray unit 5, the vehicle-mounted control unit 2 communicates with the computer 28 of the central control unit 1 to control the timing of spraying and loosening the soil, and the computer 28 of the central control unit 1 stores program control for controlling the timing of spraying and loosening the soil. Preferably, it also comprises a humidity sensor 23, the humidity sensor 23 is integrated in the plant protection device, and of course, a camera 33 is provided on the plant protection vehicle 6 to feedback real-time image information.

[0028] The working principle and use process of the present invention are as follows: the mobile terminal 25 remotely communicates with the computer 28 of the central control unit 1, and the computer 28 communicates with the plant protection vehicle 6 to programmatically control the irrigation and loosening of the soil according to the stored spraying and loosening timing. Preferably, the loosening unit 4 includes a boom 7, a rod 8 hinged to the boom 7, a return spring 9 connected between the boom 7 and the rod 8, a T-bar 10 slidably connected to the rod 8, and a telescopic rod 11 fixedly connected to the rod 8, the telescopic rod 11 is connected to the lifting structure 3, one end of the T-bar 10 is connected to the boom 7, the other end of the T-bar 10 is connected to an electric cylinder 12, and the electric cylinder 12 is fixedly connected to the telescopic rod 11; the boom 7 is connected with a rotating shaft 13 through a single free rotation, a passive wheel 14 is provided at the upper end of the rotating shaft 13, and the transmission shaft is detachably connected to a fork body 15, a double wheel 30 is provided on the hinge shaft at the hinge of the boom 7 and the rod 8, the passive wheel 14 is connected to the double wheel 30 by a belt 29, and a driving motor 16 is provided on the telescopic rod 11, and a driving wheel 32 connected to the double wheel 30 is provided on the motor 16. When it is necessary to loosen the soil, the lifting mechanism rises and drives the telescopic rod 11 to rise. At this time, the plant protector is higher than the flower pot, and then the electric cylinder 12 extends. The outer movable arm 7 of the T-bar 10 moves inward under the action of the reset spring 9, and finally the fork body 15 is located inside the flower pot. Then the motor 16 is started, and the motor 16 drives the driving wheel 32, the double wheel 30, the passive wheel 14, and the rotating shaft 13 in sequence, so that the rotating shaft 13 rotates on the movable arm 7, and the fork body 15 on the rotating shaft 13 rotates with the rotating shaft 13. At the same time, the lifting mechanism moves down a certain distance of 5-10 cm to loosen the compacted layer. After the loosening of the soil is completed, it can be reset according to the above-mentioned reverse process. Furthermore, the inventor cleverly provides a double wheel 30 on the hinge shaft at the hinge of the boom 7 and the rod 8, and drives the belt 29 wheel through the double wheel 30 to drive the rotating shaft 13. This makes it possible that no matter how the boom 7 moves, the transmission relationship between the double wheel 30 and the belt 29 wheel will not be affected, which greatly simplifies the structure of the transmission system. When the boom 7 is opened or closed, the axis of the belt 29 wheel moves in a circular arc relative to the hinge, so the distance between them remains unchanged. This can achieve the above-mentioned transmission relationship between the double wheel 30 and the belt 29 wheel will not be affected no matter how the boom 7 moves, which greatly simplifies the structure of the transmission system and achieves good results. At the same time, due to the simplified structure, the weight of the plant protection device is reduced, the "biased weight" phenomenon is reduced, and the plant protection vehicle 6 is not easy to overturn.

[0029] Preferably, the motor 16 is located at one side of the intersection of the rod 8 and the telescopic rod 11 to make the structure compact, reduce unnecessary transmission structural parts, and make the structure more reasonable.

[0030] Preferably, the spray unit 5 includes a branch pipe 17 fixedly connected to the boom 7, a water supply pipe 18 connected to the branch pipe 17, a water supply box 19 connected to the water supply pipe 18, and a flow meter 20. A water supply pump 21 is provided inside the water supply box 19, and the water outlet of the water supply pump 21 is connected to the water supply pipe 18. The water supply pump 21 and the flow meter 20 are electrically connected to the vehicle controller. A spray head 22 is provided at the lower part of the branch pipe 17. The water supply pipe 18 is arranged along the telescopic rod 11 and the lifting structure 3. The water supply pipe 18 located there is connected by a threaded pipe 26 to adapt to the extension and contraction of the lifting structure 3. The branch pipe 17 and the water supply pipe 18 are connected by a threaded pipe 27 to adapt to the movement of the boom 7. The humidity sensor 23 is fixedly connected to the electric linear thruster 24, and the electric linear thruster 24 is fixed to one side of the fork body 15. When the electric linear thruster 24 is retracted, the ground end of the humidity sensor 23 is higher than the fork teeth of the fork body 15. Working principle: Watering, loosening soil and humidity detection are highly integrated, and the loosening soil and humidity monitoring functions have a synergistic effect with the functional structure. Specifically, after the fork body 15 loosens the compacted culture soil, its surface is no longer hard, so that the humidity sensor 23 can smoothly enter the soil to complete the detection. When detecting the culture soil, the electric linear propeller 24 drives the humidity sensor 23 to extend, and retracts it after completion. The humidity sensor 23 is fixedly connected to the extended end of the electric linear propeller 24.

[0031] While the structure of the above scheme remains unchanged, the inventor has installed a weather forecast system in the computer 28 of the central control unit 1 to determine whether the viewing vegetation needs to be watered on rainy days; in order to ensure the smooth operation of the plant protection vehicle 6, the plant protection vehicle 6 is preferably a tracked vehicle, which is a prior art and will not be described in detail here.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
